Don't know about nukeproof but my clarkes (hope) pads didn't last long. For some from uberbikecomponents recently and they seem great. Quiet and long lasting plus at least as good as the superstar kevlars

Brake pads is one area I won't skimp on any more. Of every component on the bike, brakes are like the most safety critical part.

I used 2pr of sintered pads from that cheap place that I won't mention on here. Stopping power was naff compared to stock Formula organic, and in sub 300km in Morzine they were worn to the point that the metal spring bit was contacting the discs! Didn't have time to throw them away! Had to do a roadside pad change just to get home.

If I'm gonna save £20 on a 2 grand bike, it'll be somewhere else. I want the best, regardless of cost.
